SASH-FAS'TENER.

SPECIFICATION forming part of Letters Patent No. 505,341. dated September 19, 1893.

Application filed April 15, 1893. Serial No. l170,412. (No model.)

To all whom, it may concern:

Be it known that I, ELZIE AMENT, a citizen of the United States, residing at Rogers Park, in the county of Cook, State of Illinois, have invented certain new and useful Improvements in Sash-Fasteners, of which the following is a specication, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in sash fasteners or locks of that class comprising a bolt with means for moving it in the direction of its length, and a guide or keeper acting in conjunction with said bolt to lock the sash.

It has for its objects among others to provide a simple and cheaply constructed sash fastener and lock that can be readily applied to a window and which will serve to draw the two sashes together and lock them and which will also hold the sash partly open if desired.

Other objects and advantages of the invention will hereinafter appear and the novel features thereof will be specifically defined by the appended claims.

The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this specification, and in which- Figure -l is a perspective view showing my improved sash fastener in one of its various positions. Fig. 2 is a longitudinal section through the device. Fig. 3 is a section at right angles to Fig. 2. Fig. l is a front elevation of a portion of a window showing another application of the invention.

Like letters of reference indicate like parts throughout the several views.

My invention is applicable to various uses; it may be arranged upon the top of the lower sash with the guide upon the face of the up` per sash; in this position it serves to lock the two sashes together and the lower sash can be locked part way up or the upper sash locked part way down, or both locked open a little distance; or instead of being thus arranged, the guide may be on the lower sash near the lower end and the bolt and its operating mechanism secured to the side of the frame. The guide is open at one end so as to permit of the sash being opened as far as desired. It the guide is arranged near the lower end of the sash the open end should be downward, but if the guide is arranged near the upper end of the sash the open end should be uppermost; when the lock is on the top of the lower sash and the guide on the upper sash the open end should be uppermost. I have shown two of the different ways of applying the device.

Referring now to the details of the drawings by letter, A designates a channeled guide of any desired length, provided with the holes a for the reception of the screws or other means a by which it is secured in place. It is formed with the longitudinal slot A open at one end as seen at a2 and that end prefer ably beveled or tapered as seen in Figs. l, 3 and 4 to facilitate the entrance of the head of the bolt into the slot as will hereinafter appear. The flanges 0,3 upon opposite sides of the slot A are provided upon their inner faces with the notches or corrugations a4 as seen best in Fig. 3.

B is acasting or base provided withaflange b having holes b for the reception of the screws or other means b2 which fasten it in place. This casing or base is provided with a longitudinal chamber or bore B in which is arranged to slide the bolt C having a neck c and beyond the neck a head C which is oppositely notched or toothed as seen at c2 in Fig. 3, the opposite end of the bolt being chambered as seen at c5 in Fig. 2 and this chamber screw threaded to receive the threaded portion of the screw D which has a milled head or thumb piece D outside the case as shown in Figs. 2 and 3.

The bottom wall of the chamber of the case Bis provided with a longitudinal slot d in which works a pin or screw d heldin the bolt and which serves to guide the bolt, to prevent its turning in the bore and to limit its movement.

In order to prevent the entire withdrawal of the screw I provide the same within the chamber or bore with an annular groove cinto which projects a screw E held in the bottom wall of the said chamber as seen in Fig. 2 which permits of the necessary movements of the screw and yet will not permit its entire removal until the screw is removed from between the walls of the groove.

I preferably employ a left hand thread on the screw so that by turning to the right will IOO tighten the clamp and to the left unlock or loosen the same; I also employ acoarse pitch so that one revolution or less of the screw will be sufficient to lock or unlock the same.

The operation will be readily understood from the foregoing description when taken in connection with the annexed drawings, and a further detailed description thereof is not deemed necessary.

Modifications in detail may be resorted to without departing from the spirit of the invention or sacrificing any of its advantages.

Working through a slot on the base, and a What I claim as new is- 1. The combination with a guide with'a slot open at one end and having notched flanges, of a base with a sliding bolt with ahead, and a screw mounted for rotation and held against longitudinal movement and engaging said bolt to actuate the same and having a head whereby it may be turned, as set forth.

2. The combination with a base with securing flanges and a longitudinal bore, of a bolt arranged to slide in said bore and provided with a head and a neck, and at `the other end a screw threaded socket, and a screw engagportion extended outside the bore for its manipulation and means for preventing longitudinal movement of the screw, substantially as specified.

3. The combination with a guide with a slot open at one end and flanges notched upon their in ner faces, of a base with a longitudinal bore and securing flanges, a bolt sliding within said bore and having a neck and a head toothed upon its opposite edges a pin in said bolt screw engaging one end of said bolt to actuate the same and means permitting rotation but preventing longitudinal movement of said screw, substantially as shown and described.

In testimony whereof I aix my signature in presence of two witnesses.

ELZIE AMENT.
